Deprecated QuickTime Codecs Temporary Fix

I saw this on the Apple Support Forums and thought it would be of interest here:

[westinmylifeaway] "You can re-enable many of the legacy codecs usable in QuickTime Player 7 with the following [Terminal commands]...

qtdefaults write LegacyVideoCodecs ApplePlanarRGB enabled
qtdefaults write LegacyVideoCodecs SorensonVideo enabled
qtdefaults write LegacyVideoCodecs SorensonVideo3 enabled
qtdefaults write LegacyVideoCodecs AppleBMP enabled
qtdefaults write LegacyVideoCodecs AppleCinepak enabled
qtdefaults write LegacyVideoCodecs AppleH261 enabled
qtdefaults write LegacyVideoCodecs AppleH263 enabled
qtdefaults write LegacyVideoCodecs AppleMotionJPEGA enabled
qtdefaults write LegacyVideoCodecs AppleMotionJPEGB enabled
qtdefaults write LegacyVideoCodecs ApplePNG enabled
qtdefaults write LegacyVideoCodecs AppleNone enabled
qtdefaults write LegacyVideoCodecs AppleVideo enabled
qtdefaults write LegacyVideoCodecs AppleGraphics enabled
qtdefaults write LegacyVideoCodecs AppleTGA enabled
qtdefaults write LegacyVideoCodecs AppleTIFF enabled
qtdefaults write LegacyVideoCodecs AppleComponentVideo enabled
qtdefaults write LegacyVideoCodecs AppleJPEG2000 enabled
qtdefaults write LegacyVideoCodecs ApplePixlet enabled

If you also want to enable all of the “legacy audio codecs” you can copy this line to your terminal:
qtdefaults write LegacyAudioCodecsEnabled yes
More details on the original post at https://discussions.apple.com/message/18075187#18075187"

These should enable both QTPX and QuickLook playback support (following a logout/login), though I have not tested this yet. This fix should only be considered temporary for Mavericks, as the next major rev of OS X may very well not support some or all of these legacy codecs at all. It is still a good idea to start transcoding your old content to modern supported codecs.

Best,
Andy
